What merchants say about Restock Alert
“Handles both price drop alerts and back in stock alerts. Finding an app that does price drop alerts without requiring the customer to log into a store account was difficult. We wanted something where the customer can input just an email address and get an alert at that email address without needing an account. This app does the job perfectly. The developers have also been very responsive and good to work with, and have implemented features we have requested. They are clearly professionals.”
